Comparing optical performance of a wide range of perovskite/silicon tandem architectures under real-world conditions

Since single junction c-Si solar cells are reaching their practical efficiency limit. Perovskite/c-Si tandem solar cells hold the promise of achieving greater than 30% efficiencies. In this regard, optical simulations can deliver guidelines for reducing the parasitic absorption losses and increasing the photocurrent density of the tandem...

Optical characterization of poly-SiO_x and poly-SiC_x carrier-selective passivating contacts

The optical modelling for optimizing high-efficiency c-Si solar cells endowed with poly-SiO_x or poly-SiC_x carrier-selective passivating contacts (CSPCs) demands a thorough understanding of their optical properties, especially their absorption coefficient. Due to the mixed phase nature of these CSPCs, spectroscopic...
